Unable to connect to a database on a shared drive - UCanAccess

I've setup my application to connect to a Access database through UCanAccess however I'm unable to connect to a database that is located on the shared drive. See below for examples.

String databasePath = "jdbc:ucanaccess://C:/Desktop/MyDB.accdb" \\\\ this works
String databasePath = "jdbc:ucanaccess://servername/etc/MyDB.accdb" \\\\ does not work and throws no suitable driver found exception

Interesting enough when I map my folder on the shared drive to some letter e.g. P: - it successfully connects.
